Podocarpus milanjianus

Podocarpus milanjianus is the most widespread African podocarp.^[2] It is found in Angola, Burundi, Cameroon, Republic of the Congo, Democratic Republic of the Congo, Kenya, Malawi, Mozambique, Nigeria, Rwanda, Sudan, Tanzania, Uganda, Zambia, and Zimbabwe.^[1]

It grows in evergreen tropical montane rainforests, cloud forests, and high-elevation dwarf forests, between 900 and 3,250 meters elevation.^[2]

The tree is widespread and locally plentiful, and is rated "least concern" in the IUCN Red List of Threatened Species.^[1]

Podocarpus milanjianus is closely related to Podocarpus latifolius. Whether they are a single or two separate species is not settled. Some authorities treat the South African populations as Podocarpus latifolius, and those elsewhere in Africa as Podocarpus milanjianus. Others treat them as a single species, Podocarpus latifolius.^[2]

A 2020 study sampled DNA from Podocarpus latifolius and Podocarpus milanjianus trees, gathered from 88 sites across Africa. They concluded that all populations sampled constituted a single species: "As South African samples (P. latifolius) did not form a clade separated from the other clades (P. milanjianus), we confirm that the two taxa can be considered as synonyms." The authors concluded that the species originated in East Africa. The western populations, in the highlands of Cameroon and Nigeria and in the Angolan highlands, diverged from the other populations around 300,000 years ago, and the species reached its current distribution pattern about 200,000 years ago.^[3]

Podocarpus milanjianus is valued as a timber tree, both commercially and artisanally. It produces straight pale yellow timber, which is fine-grained and easily sawn and worked.^[2]

The tree is used to provide shade in tea, coffee, cocoa, and banana plantations, in reforestation projects, and as a roadside or ornamental tree.^[2]

Parts of the tree have minor local uses as food (the fleshy receptacles at the seed base) or medicine (bark or leaves).^[2]
